Ridley Scott's prequel to Aliens included a presentation at TED this year by Peter Weyland - the fictional character played by Guy Pearce - pretending it was from TED 2023. (Minor nit: This looks like actual film, versus the digital video often used for TED videos.)

And it's just part of an elaborate, transmedia campaign that so far includes elements like fake business cards that lead to YouTube videos and Facebook conversations. And don't miss this corporate video for Weyland' Corp's new android, David (below).

As Simon Pulman, CEO of Starlight Runner Entertainment, writes in Ad Age, this effort - from Scott and "Lost's" Damon Lindelof - makes the advertising for the film an extension of the film rather than purely promotional. Best of all, it makes fans part of the effort, enlisting them to spread word of, and dissect, each new component of the campaign.

In my book THE ON-DEMAND BRAND, I look at how Lenelof and then-head of marketing for ABC Entertainment, Mike Benson, used transmedia storytelling to fuel fandemonium among "Lost" fans in the (often long) periods between seasons.

Prometheus looks very cool - and the campaign promoting it looks cooler still.
